'4. Never conceal the _general_ intention of the treatment; that is, whether it be adopted with a view to cure, or only to mitigate the disease, or merely to alleviate a symptom or symptoms. '5. Never prescribe medicines more powerful than are necessary; or continue a powerful medicine longer, or repeat it oftener, than the disease actually requires. '6. Never attribute to the medicine-giving part of the management of a successful case more than its due share of credit.' We have called this a new system, but a new system is nothing without a name; and we therefore beg leave to suggest one, made up, like the others, of a Greek compound. First, we have Allopathy, another suffering; then Homoeopathy, the same suffering; then Hydropathy, water-suffering; and now let us have Anapathy, no suffering at all. APPLICATION OF THE SIRENE TO COUNT THE RATE AT WHICH THE WINGS OF INSECTS MOVE. The buzzing and humming noises produced by winged insects are not, as might be supposed, vocal sounds. They result from sonorous undulations imparted to the air by the flapping of their wings. This may be rendered evident by observing, that the noise always ceases when the insect alights on any object. The sirene has been ingeniously applied for the purpose of ascertaining the rate at which the wings of such creatures flap. The instrument being brought into unison with the sound produced by the insect, indicates, as in the case of any other musical sound, the rate of vibration. In this way it has been ascertained that the wings of a gnat flap at the rate of 15,000 times per second. The pitch of the note produced by this insect in the act of flying is, therefore, more than two octaves above the highest note of a seven-octave pianoforte.--_Lardner's Handbook_. A WELCOME SACRIFICE. BY THE REV. JAMES GILBORNE LYONS, LL.D. Vain is the blood of rare and spotless herds, Pastured in meads where blue Clitumnus shines; Vain are sweet gums from lands that Indus girds, Or diamonds sought in deep Brazilian mines; Vain are Iberian fruits, and perfumed flowers, Rich as a Grecian sunset's purest dyes, If deemed, when worship claims thy holiest hours, For HIM IN HEAVEN fit gift or sacrifice. The flocks that roam on thrice ten thousand hills, Each living thing that moves on shore and sea, The gems and gold which gleam in caves and rills, Saba's low shrub, and Lebanon's proud tree, The fragrant tribes that spring on cliff and field, That flush the stream, or fringe the smooth lake's brim, Breathe, burn, and bloom, at His high will revealed, And own with joy their Light and Lord in Him.
